Using substitution what is the value for x for the equations 2x+y=-3 and

y=4x+6? *

X3

x=3/2

O

x=0

Answer: x = - 3/2

Explanation:

Hi, to answer this question we have to solve the system of equations:

2x + y = -3

y=4x+6

Substituting y=4x+6 in the first equation:

2x + (4x+6) = -3

Solving for x:

2x + 4x+6 = -3

2x+4x = -3-6

6x = -9

x = -9/6

x = - 3/2

In conclusión, the value of x is - 3/2.
